How to Initialize third party JavaScript asynchronous library before loading AngularJS

I'm facing problem while initializing a third party JavaScript API (iHUB) inside RUN method of AngularJS. Currently the code is behaving in asynchronous mode. I want IHUB to first initialize and then AngularJS route/controller should get called. (Is it possible to make utilization of the callback method provided by IHUB ?)
var nameApp = angular.module('nameApp', ['ngRoute']);
nameApp.run(['$window', 'myService', function($window, myService) {
//initialize IHUB
var actuate= new actuate();
actuate.initialize('http://localhost:8700/iportal', settings.reqOps, "user", "pwd", callback);
function callback(){
alert('started!!');
}
}]);
nameApp.config(['$routeProvider', function($routeProvider) {
$routeProvider.
when('/:tabname', {
templateUrl: 'pages/analyticsDetail.html',
controller: 'tabDetailCtrl'
}).
when('/:tabname/:reportName', {
templateUrl: 'pages/analyticsDetail.html',
controller: 'reportDetailCtrl'
}).
otherwise({
redirectTo: '/Buy Side Dashboard'
});
}]);

There is only one way to achieve a "real" before AngularJS initialization behavior by using angular.bootstrap();. This allows you to initialize your AngularJS application manually.
Note: You should not use the ng-app directive when manually bootstrapping your app.
> Fiddle demo
View
<div ng-controller="MyController">
Hello, {{greetMe}}!
</div>
Application
angular.module('myApp', [])
.controller('MyController', ['$scope', function ($scope) {
$scope.greetMe = 'World';
}]);
var actuateDummy = {
initialize: function (callback) {
setTimeout(callback, 2500);
}
};
actuateDummy.initialize(function () {
angular.element(function() {
angular.bootstrap(document, ['myApp']);
});
})
This is an other approach which uses the resolve state of ui-router. This service only initializes iHUB if it not has been initialized yet:
This service also returns the actuate object. In that way you can use it in your controller or components after init.

View
<nav>
<a ui-sref="state1">State 1</a>
<a ui-sref="state2">State 2</a>
</nav>
<div ui-view></div>
AngularJS Application
var myApp = angular.module("myApp", ["ui.router"]);
myApp.config(function($stateProvider, $urlRouterProvider) {
$stateProvider.state("state1", {
url: "#",
template: "<p>State 1</p>",
controller: "Ctrl1",
resolve: {
iHubInit: function(iHubService) {
return iHubService.init()
}
}
}).state("state2", {
url: "#",
template: "<p>State 2</p>",
controller: "Ctrl2",
resolve: {
iHubInit: function(iHubService) {
return iHubService.init()
}
}
});
});
myApp.controller("Ctrl1", function($scope, iHubService) {
console.log("Ctrl1 loaded.");
});
myApp.controller("Ctrl2", function($scope, iHubService) {
console.log("Ctrl2 loaded.");
});
myApp.service('iHubService', ["$q", function($q) {
this.iHubServiceInitialized = false;
this.actuate = null;
this.init = function() {
if (!this.iHubServiceInitialized) {
//Init
var self = this;
var deferred = $q.defer();
this.actuate = new actuate();
//initialize
this.actuate.initialize('http://localhost:8700/iportal', settings.reqOps, "user", "pwd", function() {
self.iHubServiceInitialized = true;
deferred.resolve(self.actuate);
});
return deferred.promise;
} else {
return this.actuate;
}
}
}]);

Try to add a resolve attribute when configuring your route provider like below:
var nameApp = angular.module('nameApp', ['ngRoute']);
nameApp.config(['$routeProvider', function($routeProvider) {
$routeProvider.
when('/:tabname', {
templateUrl: 'pages/analyticsDetail.html',
controller: 'tabDetailCtrl',
resolve: {
ihubInit: ['iHubService', function (iHubService) {
return iHubService.init();
}]
}
}).
when('/:tabname/:reportName', {
templateUrl: 'pages/analyticsDetail.html',
controller: 'reportDetailCtrl',
resolve: {
ihubInit: ['iHubService', function (iHubService) {
return iHubService.init();
}]
}
}).
otherwise({
redirectTo: '/Buy Side Dashboard'
});
}]);
nameApp.service('iHubService', ["$q", function($q){
this.init = function() {
var deferred = $q.defer();
var actuate= new actuate();
actuate.initialize('http://localhost:8700/iportal', settings.reqOps, "user", "pwd", callback);
function callback(){
deferred.resolve();
}
return deferred.promise;
}
}]);

Angular service that is instantiated on every page change/request

So, I'm making my first steps in AngularJS (1.5) and I'm trying to build a feature that will let me change few things in my layout based on the route.
As far as I understood I needed a service for this. Basically the setup I have is:
'use strict';
/* App Module */
var app = angular.module('app', [
'ngRoute',
'appControllers',
'AppServices'
]);
app.config(['$routeProvider', function($routeProvider) {
$routeProvider.when('/', {
template: '<h1>Home page</h1>',
controller: 'MainController'
}).when('/page', {
template: '<h1>Page</h1>',
controller: 'PagesController'
}).otherwise({
redirectTo: '/'
});
}]);
var appControllers = angular.module('appControllers', []);
appControllers.controller('MainController', ['$rootScope', 'AppSetup', function($scope, AppSetup) {
$scope.app = AppSetup.build();
console.log('home');
}]);
appControllers.controller('PagesController', ['$rootScope', 'AppSetup', function($scope, AppSetup) {
AppSetup.setProperties({
meta: {
title: 'My Second Page'
}
});
console.log('page');
$scope.app = AppSetup.build();
}]);
var AppServices = angular.module('AppServices', []);
AppServices.service('AppSetup', [function() {
var properties = {
meta: {
title: 'My App • Best of the best'
}
},
styles;
this.setProperties = function(input) {
this.properties = angular.extend(properties, input);
};
//TODO: This will override app-wide styles.
this.setStyles = function(input) {
this.styles = angular.extend({}, input);
};
this.build = function() {
return {
properties: properties,
styles: styles
};
};
}]);
Plunkr here
So I have one defined properties object and want to override it when I visit a page. The problem is that when I go back to home, it doesn't set the default value. Obviously it's instantiated once the page is loaded and then remains the same until changed.
What's the best approach to do this?
I have tried adding a listener to the route, as #Raul A. suggested, but it's not working. Output from console:

You can use the $routeChangeSuccess event if you are using routing and make changes in the function watching for it:
$rootScope.$on("$routeChangeSuccess", function(currentRoute, previousRoute){
//Do you changes here
});

Angular Directive update view from template url

I have started learning angularjs recently and I am doing some stuff. I tried to use this actice example, especially 3 example. I tried to read from tempate files by their url but I couldn't. I got bellow code (here only peace of code which I changed):
var app = angular.module('app', []);
app.value('MultiViewPaths',
{'/' : {
content : {
templateUrl : './templates/_header.html'
},
secondaryContent : {
templateUrl : './templates/_secondaryContent.html',
controller : 'ListUsersCtrl'
}
},
'/cats' : {
content: {
templateUrl : 'templates/_headerCats.html',
controller : 'ListCatsCtrl'
},
secondaryContent : {
templateUrl : 'templates/_secondaryContentCats.html',
controller : 'CatOfTheMinuteCtrl'
}
}
});
app.directive("ngMultiView", ['$rootScope', '$compile', '$controller', '$location', 'MultiViewPaths','$templateCache', function($rootScope, $compile, $controller, $location, MultiViewPaths, $templateCache){
var getTemplate = function(templateUrl) {
console.log(templateUrl)
var template = $templateCache.get(templateUrl);
console.log(template)
return template
}
return {
terminal: true,
priority: 400,
transclude: 'element',
compile : function(element, attr, linker){
return function(scope, $element, attr) {
var currentElement,
panel = attr.ngMultiView;
$rootScope.$on('$locationChangeSuccess', update);
update();
// update view
function update(evt, newUrl, oldUrl){
if(!newUrl){ return }
var url = newUrl.match(/#(\/.*)/),
match, template, controller;
match = url ? MultiViewPaths[url[1]] : MultiViewPaths['/'];
template = getTemplate(match[panel].templateUrl);
console.log(template)
controller = match[panel].controller;
if(template){
var newScope = scope.$new(),
locals = {},
newController = controller;
linker(newScope, function(clone){
clone.html(template);
$element.parent().append(clone);
if(currentElement){
currentElement.remove();
}
var link = $compile(clone.contents());
currentElement = clone;
if (newController) {
locals.$scope = newScope;
var controller = $controller(newController, locals);
clone.data('$ngControllerController', newController);
clone.children().data('$ngControllerController', newController);
}
link(newScope);
newScope.$emit('$viewContentLoaded');
});
}else{
//cleanup last view
}
}
}
}
}
}]);
Other thing the same with example. I could not read templates inner html. Can anyone help me ?

I would recommend using uiRouter rather than ngRouter. With uiRouter you do not need to create a directive to handle changing the view for different URL parameters.
They give an example of how to do this using the $stateProvider here http://angular-ui.github.io/ui-router/site/#/api/ui.router.state.$stateProvider
templateUrl: function(params) {
return myTemplates[params.pageId]; }

AngularJS duplicates http requests

I'm doing some interfaces with AngularJS and watching the Chrome Console I detect that each http request to an API it makes for duplicate.
Is there any way to avoid this?
This is my simplified code
$http.jsonp('http://APIURL.com/api/category/menu?callback=JSON_CALLBACK').success(function(data){
$scope.categories=data.categories;
});
Full code:
var kbControllers = angular.module('kbControllers', []);
kbControllers.controller("KBHomeController", function ($scope, $http, $rootScope) {
$rootScope.header = 'Title of page';
$http.jsonp('apicall.com/api/category/menu?callback=JSON_CALLBACK').success(function (data) {
$scope.categories = data.categories;
});
});
and this is my console
any thought?

i have faced this problem, and you can resolve it like this :
check if you have declared ng-controller twice , you need to declare it just one time
check if you have declared data-ng-click , if so , you need to replace it with ng-click
that's it

This is app.js
var app = angular.module('app', [
'ngRoute','kbControllers', 'kbFilters', 'kbDirectives', 'angularytics', 'kbServices'
]).config(['$routeProvider', function($routeProvider) {
$routeProvider
.when('/',
{
templateUrl: '/assets/angular/kb/partials/home.html',
controller: 'KBHomeController'
}
).when('/category/:category',
{
templateUrl: '/assets/angular/kb/partials/category.html',
controller: 'KBCategoryController'
}
)
.otherwise({redirectTo:"/"});
}
])
And in controllers.js
var kbControllers = angular.module('kbControllers', []);
kbControllers.controller("KBHomeController", function ($scope, $http, $rootScope, Menu) {
$rootScope.header = 'Atención al cliente - Movistar Argentina';
$http.jsonp('http://APIURL.com/api/category/menu?callback=JSON_CALLBACK').success(function(data){
$scope.categories=data.categories;
});
})
and my view /partials/home.html
[...]
<li ng-repeat="category in categories"><i class="{{category.icon}}"></i><span>{{category.name}}</span></li>
[...]

How can you manually inject route resolve data inside a controller?

I have 2 routes that share a controller, one needs data resolved prior to the view loading, and the other does not need the resolved data.
Routing segment example:
...
when('/users', {
controller: 'UsersCtrl',
templateUrl: '/partials/users/view.html',
resolve: {
resolvedData : ['Accounts', function(Accounts) {
return Accounts.get();
}]
}
}).
when('/users/add', {
controller: 'UsersCtrl',
templateUrl: '/partials/users/add.html'
})
...
Controller example:
app.controller('UsersCtrl', ['$scope', 'Helper', 'resolvedData',
function($scope, Helper, resolvedData) {
// this works for the first route, but fails for the second route with
// unknown "resolvedDataProvider"
console.log(resolvedData);
}]);
Is there any way I can get the resolvedData in the controller without explicitly using the resolve name as a dependency? So a check can be performed?
Using the $injector does not work. I would like to do something similar to:
if ($injector.has('resolveData')) {
var resolveData = $injector.get('resolveData');
}
However this does not work even for the route that has the resolveData set ('/users'):
app.controller('UsersCtrl', ['$scope', 'Helper', '$injector',
function($scope, Helper, $injector) {
// this does not work -> fails with the unknown "resolvedDataProvider" as well
$injector.get('resolvedData');
}]);
Can this be done in angularjs? Or should I just create a new controller?
Thank you.

Looks like I figured out another way to go. The resolved data is part of the $route. So you can access it using:
app.controller('UsersCtrl', ['$scope', '$route', 'Helper',
function($scope, $route, Helper) {
if ($route.current.locals.resolvedData) {
var resolvedData = $route.current.locals.resolvedData;
}
}]);

If the other route doesn't need it, just inject undefined on that route:
router:
when('/users', {
controller: 'UsersCtrl',
templateUrl: '/partials/users/view.html',
resolve: {
resolvedData : ['Accounts', function(Accounts) {
return Accounts.get();
}]
}
}).
when('/users/add', {
controller: 'UsersCtrl',
templateUrl: '/partials/users/add.html',
resolve: {
resolvedData: function() {
return undefined;
}
}
})
controller:
app.controller('UsersCtrl', ['$scope', 'Helper', 'resolvedData',
function($scope, Helper, resolvedData) {
if(resolvedData){
//set some scope stuff for it
} else {
//do what you do when there is no resolvedData
}
}]);
